In "A Synopsis of Neotropical Hylid Frogs, Genus Osteocephalus," editors William Edward Duellman and Linda Trueb curate a comprehensive exploration of one of the most vibrant amphibian genera in the Neotropical realm. The collection stands as a seminal work, melding rigorous scientific research with a clear, accessible presentation, making it an invaluable resource for herpetologists, ecologists, and conservationists alike. This anthology not only delineates the vast diversity within the Osteocephalus genus but also underscores the ecological significance of these creatures within their respective ecosystems, offering vital insight into their behavior, physiology, and the urgent conservation challenges they face. The contributions from Duellman and Trueb, both esteemed figures in the field of herpetology, reflect a deep understanding and passion for amphibian studies. Their work is part of a broader scholarly endeavor to catalog and conserve the rich biodiversity of the Neotropical region. This anthology aligns with contemporary movements in biological conservation and biodiversity studies, merging detailed scientific descriptions with broader ecological contexts, thereby illustrating the interconnectedness of species and their habitats. "A Synopsis of Neotropical Hylid Frogs, Genus Osteocephalus" is recommended for anyone seeking to deepen their understanding of Neotropical amphibian diversity and conservation. Through its engaging narrative and meticulous research, it offers readers a unique opportunity to explore the complexities of the Osteocephalus genus, highlighting the collaborative effort required to preserve our planet's biodiversity. This collection is a testament to the richness of life and the critical need for continued scientific inquiry into the natural world.

Toothed pterosaurs are known from England since the 19th Century, through the works of James Scott Bowerbank (1797?1877) and Richard Owen (1804?1892). Harry Govier Seeley (1839-1909) soon realized that the English pterosaurs were distinct and referred several species in the genus Ornithocheirus. The fragmentary nature of the material, competing taxonomic proposals, synonymisations, and misunderstandings, lead to a very controversial taxonomic scenario. This monograph reviews thirty species that, at some point, were referred to Ornithocheirus. From these, fourteen are considered valid and belonging to five genera, three of them new. These genera are exclusive to the Cretaceous of England. Sixteen species are deemed undiagnosable. Descriptions and illustrations of all these species are provided. For the first time, a large number of species of the Ornithocheirus complex was included in a phylogenetic analysis and it is shown that most of them comprise a newly diagnosed clade, Anhangueria, with Brazilian and Chinese taxa.

This book chronicles the discovery and analysis of animal fossils found in one of the most important paleontological sites in the world—Porcupine Cave, located at an elevation of 9,500 feet in the Colorado Rocky Mountains. With tens of thousands of identified specimens, this site has become the key source of information on the fauna of North America's higher elevations between approximately 1 million and 600,000 years ago, a period that saw the advance and retreat of glaciers numerous times. Until now, little has been understood about how this dramatic climate change affected life during the middle Pleistocene. In addition to presenting state-of-the-art data from Porcupine Cave, this study also presents groundbreaking analysis on what the data from the site show about the evolutionary and ecological adjustments that occurred in this period, shedding light on how one of the world's most pressing environmental concerns—global climate change—can influence life on earth.

The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

This beautifully illustrated 2007 volume describes the flora and fauna of the Lower Cretaceous Crato Formation of Brazil, one of the world's most important fossil deposits, exhibiting exceptional preservation. Covering a wide range of invertebrates, vertebrates and plants, it is an essential reference for researchers and enthusiasts interested in Mesozoic fossils.
